At least in the United States, there is a ton of misinformation about circumcision. Long story short, it's routinely done to infant boys, and is commonly thought to be healthier. In truth, there is little to no evidence of any medical benefits from circumcision.
Even further, many doctors, including pediatricians, aren't taught proper care for foreskins. A classic example is that in young boys the foreskin is fused to the head of the penis. It loosens as they get older, and usually is retractable around puberty. It's important not to forcibly retract the foreskin until this happens, or it can cause complications, including phimosis. Many pediatricians don't know this, and will retract the foreskin during a checkup, or will give the parents bad advice and tell them to clean under the foreskin during bath time.
